• Two measuring profiles cover 50mm and 90mm king pins.
• Metal gauge body.
• Pack quantity: 1 gauge.

Specifications and Materials

Metal king pin inspection gauge for 50mm and 90mm king pins.

Part number: G-KP50-90.

See the JOST service tools technical page for manufacturer guidance on king pin wear gauges.

Compatibility and Fitment

Confirm the king pin is either 50mm (2″) or 90mm (3½”) before use. Position the gauge against the king pin being inspected and follow the applicable fifth wheel service procedure when assessing wear.

Compliance and Safety

Keep the gauge and measuring surfaces clean and undamaged so wear checks are not affected by debris, burrs or damage.

Trailer Applications

Workshops use this gauge when inspecting heavy trailer king pins and fifth wheel coupling systems in the 50mm and 90mm sizes.

Why Choose ICS Trailers

The main selection check is the king pin diameter being inspected. This gauge covers both 50mm and 90mm pins, which removes the need to choose between separate size-specific gauges. ICS Trailers can help compare the king pin size and photos of the coupling area before you order.

• One gauge covers both supported king pin diameters.
• We can also help identify surrounding fifth wheel and king pin service components from measurements and photos.
